Don’t think about what has not happened. What has not happened has not happened. Simple. It has not arrived. So why worry, why fear? Of course, when it comes into your Life, you have to, and must, deal with it. But why lose your precious present, your sleep, thinking about the unborn future? Living in the now is not an art. It is an absolute necessity for you to be happy. It is like breathing. You (can) breathe only in the now – your having breathed in the past is over, it is done with; and your breathing in the future is irrelevant at the moment. The only Life you have is what you have in the now. So, stay here. Be present. Be happy with what is.
